CHS 76x9 GOST · Weight & Dimensions

GOST, cold-formed sections · Circular Hollow Section

Circular Hollow Sections (CHS) are round tubular profiles with the most efficient cross-section for compression. Used for columns, trusses, and architectural structures.

Also known as: Caño estructural redondo (Argentina)

The CHS 76x9 steel profile weighs 14.9 kg/m (9.99 lb/ft). Cross-sectional area: 1,894.38 mm². Moment of inertia Ix = 108.216 cm⁴, Iy = 108.216 cm⁴.
